IMPROVEMENT IN MACHINES FOR NAILING BOXES.

Specification forming part of Letters Patent No. 155,284, datedSeptember 22, 1874 application filed July 20, 1874.

To all whom it may concern:

Be it known that I, MATHEW BLASER, of Detroit, in the county of Wayneand State of Michigan, have invented an Improved Machine for NailingBoxes, of which the following is a specification:

The nature of my invention relates to an improvement in that class ofmachines which are used for nailing together the sides and ends ofcigar-boxes and other tight packages, wherein three or more nails can bedriven by a single movement of a treadle'; and it consists in thepeculiar construction of the machine, and in the adjustability of thedevices which adapt it to the nailing together of the parts of boxes ofvarious sizes, as more fully hereinafter set forth.

Figure l is a perspective view. Fig. 2 is a cross-section of the tableat a: a. Fig. 3 is a longitudinal vertical section at 3 y.

In the drawing, A represents a suitable frame, which supports a table,B, across the rear end of which I- journal a rock-shaft, 0, having along arm, D, and a shorter one, D. To the former is pivoted aconnecting-rod, E, whose lower end is pivoted to a treadle-lever, F. Tothe short arm D is pivoted a link, G, having an eye in its front end,which is pivoted between the jaws of a sliding hammer, H, by a longtransverse pin,.I, to which two other hammers, H, are pivoted, one ateach side of the hammer H, by sliding the eye of each upon said pin.

The hammer H slides in a long box-like bearing, J, secured to the table,while the side hammers slide in boxes J, secured to plates K, which arelaterally adjustable in recesses cut in the table-top, being secured atany point by a set-screw, a, passing through a slot, b, in each plate K.As the hammerboxes are adjusted to or from the central one, so thehammers H are adjustable on the pin I. The hammers are retracted by aspring, L, or its equivalent, until their striking-faces are flush withthe ends of their bearin gs, except the lower part of each, which isextended like a trough to form a receptacle, 0, the length of the nail,brad, or tack used.

M is a rest on the front end of the table. parallel with the ends of thehammers. It is adjustable to receive box sides of varying widths betweenit and the hammer.

In the present instance I effect such adjustment by making a parallellower part, M, to slide in dovetail ways N under the table. The part Mis longitudinally slotted t0 straddle a nut, O, pendent from the table,through which is tapped a screw, P, passing through the head of the saidrest; but it is evident that the said rest can be adjusted in a varietyof ways.

Fig. 3 shows the operation of the hammers in driving the nails.

The rest M is adjusted to receive the bottom and a side of a box, or anyother two parts to be nailed, between it and the nail receptacle 0, ineach of which a nail has previously been placed. A downward movement ofthe treadle throws forward the hammers, which drive the nails home.

The hammers being laterally adjustable, the nails can be driven into thematerial at any desired distance apart.

What I claim as my invention, and desire to secure by Letters Patent, is

In a single box-nailing machine, the combination of a suitable frame, A,and platform B with a treadle, F, and rock-shaft (l, which control, byintervening rods, the horizontallysliding hammers H and H, said hammerssliding in lipped boxesJ and J, of which the latter are laterallyadjustable by means of the adjustable plates K,t0 which they aresecured, and the rest M, also adjustable by means of a stud, O, andscrew 1?, the several parts being constructed and arranged substantiallyas described, and for the purposes set forth.

MATHEW BLASER.
